Another of my favourites is this 1974 Triumph Dolomite Sprint,  this is one of a four-car team which entered the 1974 Spa 24 Hours sponsored by Butch Tailors – the ‘Butch Racing Team’. Car no. 46 was driven by Claude De Wael & Etienne Staelpart and the team also ran the car that finished 5th overall driven by the famous pairing of Tony Dron and Andy Rouse. Whilst running very well in the top ten, this particular car (chassis 2110) unfortunately failed in the 23rd hour (listed as suspension maladies but believed to be a rear axle failure).  – I had the opportunity to drive the sister car in last year’s Historic Touring Car Challenge races at Donington & Silverstone which now fall into the Tony Dron Trophy for Group 1 cars. We had immense fun driving the Dolly and we even picked up a prize.  This one will need an overhaul as it last raced in 1981, but offers great value for fun given the estimate at £20,000 – £25,000.00

1961 Emerson Formula 1 Climax  – Now this is a rare find, apparently (Chassis number 1004) is the only surviving F1 Emeryson and even this car might not have made it, had it not been for the efforts of car restorer and showroom owner, Peter Morley who bought it in 1992 and returned it to the way it would have been when driven by Settember and Campbell-Jones in its heyday. When fully finished it was entered at the first Goodwood Circuit Revival in 1998 driven by Paul Osborn.

A highly rare and eligible racer offering a passport for Goodwood, Monaco Grand Prix Historique and other HGPCA or HSCC events. Estimate £150,000 – £180,000.

This 1973 BMW 3.0CSL Batmobile was converted from 3.0CS road car in the late 1980s by saloon racer – the late Tim Busby, and has accumulated many excellent race results over the ensuing 30 years on race tracks all over the world. In 2004 it was sold to Silverstone Auctions owner, Nick Whale, and co-owned by Ian Guest. The pair campaigned the car in Patrick Peter’s Classic Endurance Racing series “CER,” throughout Europe, including twice at Classic Le Mans in 2004 and 2006 where it won its ‘Plateau’ on both occasions. It also won the coveted Index of Performance award at the 2004 Le Mans as well as further class wins at Monza, Silverstone, and Spa. It was then sold to Alan Tice who successfully campaigned the car for two or three seasons in the Masters series, before changing hands again in 2013. The car has had a break from racing under the current owner (a serious collector) but it has had an engine rebuild by noted engine specialist Lester Owen in 2014 at a cost of £6,800, and also had the bodywork modified to Group IV type arches and a full repaint. Having completed just one track day where it covered just a handful of laps at Silverstone. The dyno sheet confirms 379bhp on tap and 306 lbs/ft torque available when Lester had finished the engine rebuild late in 2014. The original, and very rare, Kugelfischer slide fuel injection is still fitted and the car is ready to be enjoyed once again, although it will need fresh race preparation as it has had so little use over the last 3 years. Perfect for the HTCC, Masters or Peter Auto series – and estimated to fetch £100,000 – £125,000.
